You should avoid visiting a hairdresser for up to 4 weeks after the operation. For your first haircut after the hair transplant, make sure that you inform your hairdresser about the operation and show the treated areas as accurately as possible, as the transplant area will only be trimmed with scissors for the first 6 months and not with an electric razor or razor blades. The area that was unaffected by the hair transplant can be trimmed as desired. It is also important to ensure that your hairdresser adheres strictly to the hygiene regulations, especially during this time.
